GEBMICIDE LINING FOR MOUTHIECES FOR VOICE-TRANSMITTENG- INSTRUMENTS.

Specification of Letters Patent. Application filed. July 14, 1908.Serial No. 143,515.

Patented March 2, 1909.

I Be t known that i, Anonsrus A. WIL- LIAMS, a citizen of the UnitedStates, reslding atCharlotte, in the county of Meclrlenvented certainnew and useful Improvements in Gerlnicide Linings for Mouthpieces forVoice-Transmitting instruments, of which the following is aspecification.

My invention relates to an improvement in the method of making voicetransmitting mouthpieces or similar devices gerinicide or antisepticwhere disease germs are likely to breed and to be gnopagatcd from oneperson to another While in the act of talking, and my objects are-lirstzto provide a plurality of removable antiseptic or gcrinioide linings forvoice trammitting mouthpieces in order that the mouthpiece may be madeantiseptic or germv proof without reducing the maximum amplitude of thesound wave to an objectionable extent; second: to provide a means toprevent saliva from enteringihe voice transmitting clement; third: toprovide a removable means for securing said burg and State of NorthCarolina, have in i l pieces to which they are to be attached; fourth:to provide a means whereby one or more of said linings may be readilyrcoheap construction of said lining so that the same may be made cheaplyin order that they may be destroyed after being used a desired length.of time.

With these objects in view, my invention 1 consists'in certain novelfeatures of construction and arrangement of parts as will l hereinafterbe more fully described and pointed out in the claims, reference beinghad to the accompanying drawing, forming part thereof, and in whichFigure 1 is an elevation of a voice t-ansl l l l l l l l I lmittingmouthpiece showing the method of securing the linings therein byan elastic band. Fig. 2 is a view of the elastic band; Fig. 3 is asection 9-10 of Fig. 2, and shows a plurality of linings arranged in amouthpiece, and Fig. t is a view showing an individual lining.

Similar figures refer to similar" parts throughout the several views.

Referring to the figures, 1 designates a. voice transmitting mouthpieceand whichl it is desired to be made antiseptic or germ proof, and isshown as the ordinary telephone transmitting instrument 9. and to whichmy present invention is particularly applicable; 5 designates aliningmade of some cheap material, such as paper, and which is adapted to betreated with some antiseptic or germicide solution. It has the shape-ofa. frustun'i of a cone, the sides being slightly concaved so as to takethe form of the inside of the mouthpiece 1; 6 designates the upper baseof the frustnm and is provided with an aperture 11 therein. The aperture11 is of such diameter as to readily allow the sound wave to to thetransmitting element without reducing the amplitude of the sound waye toan objectionable extent, and is smaller in diameter than the upper ofthe frustum. The lower base 0!? the frustum shaped lining 3 isvertically turned forming the part 7 and is adapted to fit over theperiphery of the mouthpiece 1.

s: designates an uncompleted loop of an elastic band, preferably ofmetal, the terminal pmrtious 8 extending si'lbstantially in oppositedirection and each also forming an uncompletcd loop, which is adaptedfor finger engagement.

designates prongs which are rigidly attached to the band 1: and extendforward and inward over the end of the mouthpiece, which serves toprevent the band at from slipping hack oil the part 7 of the lining 3.

The thickness of the linings, as shown in Figs. 3 and 4-, is somewhatexaggerated, and in practice would be made of thin material. The conicalshape of these linings allows a plurality of them to be telescopedtogether, as shown in Fig. 3, and it is obvious can be readily insertedin a voice transmitting mouthpiece, as shown. The aperture 11, asheretofore described, allows the sound wave to readily pass to thetransmitting element. These linings can readily be made antiseptic orgerm proof by the ordinary methods, as are understood by those skilledin that art, and thus accomplishii'ig the aforesaid first mentionedobject of my said invention.

As shown in Fig. i, the aperture 11, in the upper base of the frustum,is smaller in diameter than the upper base, the remaining part thereforeacts as an obstruction to any saliva that may have a tendency toconverge and s to me v:
